3.3 Handling Broadcast Packets

Your IP layer should be able to handle broadcast packets (since the DHCP protocol relies on them). More specificially, it needs to provide support for IP packets sent to the limited broadcast address 255.255.255.255. Your implementation should follow these rules:

• Datagrams destined to this address must never be forwarded by a router.

• Locally generated datagrams with this destination address must be sent out over all interfaces.

• Received datagrams with this destination address must be forwarded to the transport layer. However, unreachable ports must not result in ICMP messages.
